Twenty-five is the plugin's ceiling. How many ZIPs you can actually send in one go, and how large they may be, is decided by the PHP configuration of the server this WordPress site runs on — upload_max_filesize, post_max_size, max_file_uploads and max_execution_time. A common host default of max_file_uploads = 20 caps the batch at twenty whatever the plugin allows; a small post_max_size rejects the whole submission before WordPress sees it; and a short max_execution_time can end a long run part-way through.
Check the four values under Tools → Site Health → Info → Server. Raise them in php.ini or your hosting panel if you control them, and split the batch if you do not. No plugin can lift a limit the server imposes before PHP hands it the request.
Licence keys are verified on your own server with no call home, so the plugin keeps working whether or not our site is reachable. A key is either domain-locked or valid on any site, depending on the plan you buy.
